High Prevalence of Antimicrobial Resistance and Integron Gene Cassettes in Multi-Drug-Resistant Klebsiella pneumoniae Isolates From Captive Giant Pandas (Ailuropoda melanoleuca)

Frontiers in Microbiology, 2022
Multi-drug-resistant Klebsiella pneumoniae (MDR K. pneumonia) is increasingly being reported with corresponding increase in morbidity and mortality all over the world. However, limited information is available concerning MDR K. pneumonia in giant pandas.

Photocatalytic and Biotechnological Strategies for Remediation of Persistent Organic Pollutants: Mechanisms, Toxicity, and Antimicrobial Perspectives

Environmental Toxicology, EarlyView.
ABSTRACT Persistent organic pollutants (POPs) pose significant ecological and human health risks due to their persistence, bioaccumulation, toxicity, and global distribution. Conventional remediation methods are often inadequate for achieving complete mineralization, demonstrating the need for advanced and substantial approaches.

Transmissible ST3-IncHI2 Plasmids Are Predominant Carriers of Diverse Complex IS26-Class 1 Integron Arrangements in Multidrug-Resistant Salmonella

Frontiers in Microbiology, 2018
Diverse mobile genetic elements (MGEs) including plasmids, insertion sequences, and integrons play an important role in the occurrence and spread of multidrug resistance (MDR) in bacteria.

Evolutionary and Epidemiological Characterization of Multidrug‐Resistant Escherichia coli Isolated From Pangolins in China

Integrative Zoology, EarlyView.
ABSTRACT Malayan pangolin populations have fallen to a critically endangered level, and illegal trafficking of wild pangolins is a global problem. Little is known about antimicrobial‐resistant bacteria (MDRB) harbored by pangolins, although pangolins are frequently consumed as food or used in traditional medicine. In this study, we report for the first

Integrons: Past, Present, and Future [PDF]

Microbiology and Molecular Biology Reviews, 2014
SUMMARY Integrons are versatile gene acquisition systems commonly found in bacterial genomes. They are ancient elements that are a hot spot for genomic complexity, generating phenotypic diversity and shaping adaptive responses. In recent times, they have had a major role in the acquisition, expression, and dissemination of antibiotic ...

Copy Number of an Integron-Encoded Antibiotic Resistance Locus Regulates a Virulence and Opacity Switch in Acinetobacter baumannii AB5075

mBio, 2020
We describe a novel genetic mechanism in which tandem amplification of a plasmid-borne integron regulates virulence, opacity variation, and global gene expression by altering levels of a putative small RNA (sRNA) in Acinetobacter baumannii AB5075.

Spatial Patterns and Associated Factors of Intestinal Antibiotic Resistance Genes in Farmed Bullfrogs From Selected Farms Across Major Production Regions in China

Integrative Zoology, EarlyView.
Across selected bullfrog farms in major Chinese production regions, 106 intestinal ARG subtypes were detected, with tetracycline and sulfonamide resistance genes predominating and clear farm‐level variation. High‐risk ARGs, including ermB, floR, and qnrA, were associated with heavy metals, MGEs, and opportunistic pathogens. These findings highlight the

Global Phylogeny and F Virulence Plasmid Carriage in Pandemic Escherichia coli ST1193

Microbiology Spectrum, 2022
Lower urinary tract, renal, and bloodstream infections caused by phylogroup B2 extraintestinal pathogenic Escherichia coli (ExPEC) are a leading cause of morbidity and mortality. ST1193 is a phylogroup B2, multidrug-resistant sequence type that has risen
